They're not that bad. a lot of them fell short but are foreseeable in the not-too-distant future. Some things he predicted for later ar arguably here or almost here, eg this one for 2029:

Computers are now capable of learning and creating new knowledge entirely on their own and with no human help. By scanning the enormous content of the Internet, some computers "know" literally every single piece of public information (every scientific discovery, every book and movie, every public statement, etc.) generated by human beings.

I don't know what the deletion of predictions means, but Wikipedia editors in general seem to dislike checklists.
